Since Pablo Hidalgo has confirmed that Captain Rex from the Clone Wars and Rebels was on Endor with General Solo’s strike team I wonder if he ever spoke to Luke about being commander of the clone army under Anakin.
I was watching ROTJ last night and the scene where Luke and Leia have their whole sibling talk and thought it would be so cool to see Luke walk off and Captain Rex stop him even for a brief moment to acknowledge that he was Anakin’s commander and that having once fought with the great General Skywalker he now is proud to fight alongside the Son of the great General.
